build native mobile applications using scala.js and react-native - please check https://github.com/chandu0101/sri where future work is going to take place :)
I guess the router included with scalajs-react is not possible to use since it interacts with the URL bar and possibly the DOM.
I have no experience with iOS development, but I assume it would be nice to have something similar to structrue the application. It would be extra nice if the API would be the same as for the web router.
